COMBINED SHUT OFF AND CHECK VALVE

VALVE AND CHECK PISTON

Disclosed is an integrated flow control valve and check valve arrangement for gases, and in particular an arrangement having a check piston incorporated into the outlet side of a gas valve. By incorporating the check piston in the outlet of the gas valve itself, the check piston protects the gas valve as well as the gas service against possible back flow of fluid, for example, water. For example, if the gas valve is connected by a hose to a water faucet, water cannot flow back through the gas valve and into the gas line which typically has a much lower supply pressure, e.g. 1/2 PSI, than the water supply (20 to over 100 PSI). The invention thus frustrates vandals who have been known to connect a rubber hose between a gas cock and a water faucet and then turned both items to the open position.

VALVE EQUIPPED WITH A BYPASS CHANNEL

An hydraulic or pneumatic pipeline security arrangement

A fluid passageway (A) has in its axis an obstruction (1) having several ports, one or more (2) of which provide direct passage of fluid through the obstruction whilst one or more other (3) ports are set such that when brought into axial alignment with the passageway they are closed by a spring loaded sealing device (4). When the ports providing direct passage of fluid (2) are in axial alignment fluid flow and pressure is free to be transmitted in either direction; when the other ports (3) are aligned axially with the fluid passageway, the spring loaded valve (4) permits transmission of fluid flow/pressure in one direction only and release of the pressure is prevented. In this way, when the arrangement is applied to vehicle hydraulic or pneumatic systems, brakes can be applied but not released, or clutches or automatic transmissions may be disengaged but not re-engaged whenever the ports aligned with the spring loaded valve are selected in alignment with the axis of the passageway.
